Command devices are of great importance for the man-machine interface in the area of industrial applications. For example, they are mounted in switch-boards, control panels, two-hand control panels, in lift manufacture and on materials-handling plants, including conveyors. Manual actuation of the devices starts operating sequences and functional processes or serves to bring these to an end.
Emergency stop command devices are generally connected in the safety circuit of a machine or plant and are of particular importance in terms of the control system for these. In case of a fault or accident, the secure function and quick accessibllity of Emergency Stop command devices can be crucial for saving life, limiting the degree of injury to personnel or the extent of damage to a machine.
New requirements are placed on the mode of operation of these command devices by the new harmonised European Standard EN 418 regarding functional aspects and recommendations for the arrangement of Emergency Stop equipment.

According to EN 292-2 (Device safety), movable guards must be provided with safety switches. Protective door manufacturer of bolts for protective devices work in tandem with SICK safety switches. On deliberate opening of the protective device, the N/C contact of the safety switch is opened and the hazardous motion of the machine is brought to a standstill.
Developed for harsh industrial everyday use
SICK products easily withstand harsh conditions such as impacts and vibrations. Opening, closing and locking is reliably guaranteed over a long lifetime. SICK safety switches are available in plastic or metal versions.

Description
Besides the metal-enclosed precision switch of the RET series, BARTEC also offers a series of limit switches manufacturers with plastic bodies. The enclosure is made of shock impact resistant proof plastic providing an IP 67 protection class according to IEC 60529. Due to its format several limit switches can be mounted in tandem formation requiring very little space.
This allows a multiple triggering of switching operations. The connection cable is equipped with a strain relief device, prewired and safely cast into the enclosure by means of epoxy resin. We supply this robust limit switch with a standard length of 1 m; special lengths are available on request. The integrated switching element changes over via NC contact with positive break operation. Operator protection corresponds the the GS-ET 15 requirements.
Its high vibration resistance and long life are the result of a most extensive laboratory research. The certification for hazardous areas and the high protection class granted thanks to its structural characteristics are the ideal prerequisites for its use in almost all fields of automation, mechanical and high-tec engineering.

Ex-Safety and Main Current Switches
CEAG protection switches can be protected against inadvertent switching on by our integrated locking facility for up to three padlocks in the OFF position.
To prevent manipulations, the enclosure covers cannot be opened in the locked position without destroying the enclosure itself.
All CEAG safety switches feature full AC-3 motor switching capacities and isolating properties according to EN 60947-4-1 with compulsory opening of the main current contacts; optional EMERGENCY STOP versions according to EN 60204-1 are also available. |

Explosion proof switches are used wherever the ambient conditions are such that the presence of inflammable substances, oxygen and a source of ignition are to be anticipated simultaneously. The primary applications are to be found in the chemical and petro-chemical industries as well as paint lines. Protection against explosions is often also necessary where a large collection of line powder can develop such that a movement of air can lead to a spontaneous detonation. Examples include mills, wood processing and food processing industry.

Sealed and high temperature precision switches contain a spring and set of contacts that convert mechanical energy applied to an actuator into an electrical output. Environmentally sealed switches are basic precision switches enclosed within a corrosion-resistant aluminum housing that professional seals the switch contacts from contamination. Hermetically sealed switches include those that maintain the contact in a gas-tight seal while transmitting force and motion to the switch mechanism through a metal diaphragm. High temperature versions have the switching element mounted on a ceramic base with a stainless steel enclosure. Wide variety of actuators manufacturers, terminations, circuitry configurations, electrical ratings, contact materials and operating characteristics provide application flexibility. Meet military standards. U.S., European and other approval agency allow global use.
Best Used For:
Presence/absence detection where physical contact with an object is permissible as well as applications requiring compactness, light weight, accurate repeatability and long life such as are found in aerospace agriculture, transportation, construction, marine, ordnance and command and control equipment.
